Abstract
The utility model relates to a protector for working high above the ground, which is suitable for protecting the workers who work high above the ground and operate a hack lever crane to load a big train on the forest farm. The protector is composed of a support frame, a damper spring, a carrying rope and a differential braking device. The utility model is characterized in that the damper spring can absorb the kinetic energy exerted on a safety rope by human body when fall down; the differential braking distance is short and the generated potential energy is small; the acting force exerted on the soft tissue of human body from a safety belt is small and other internal injury can not arise. The utility model has the advantages of simple structure and convenient operation, and can not influence workers in labor for doing any action. Moreover, the protector can prevent accidents of workers who work high above the ground and fall down carelessly, thereby, the personal safety of the forestry workers can be ensured.
Description
The utility model is a kind of protector of work high above the ground, is applicable to that forestry timber depot hack lever crane adorns the safeguard protection of workman's work high above the ground of big train.
Before the utility model, the workman on forestry timber depot does not have the safeguard protection facility when adorning big train, and the workman often falls tumble injury and death by accident onboard during operation, gives individual and country causes very big loss.
Generation for fear of above-mentioned accident; the utility model has designed the work high above the ground protector; this protector does not influence the exercises that the workman is taken place in work, can prevent that the workman is accidentally from the generation of work high above the ground face fallen accident, with protection forest worker's personal safety.
Protector of the present utility model is made up of (in the accompanying drawing 1) bracing frame (1), buffer spring (2), ropeway carrying-rope (3), the differential braking device (4) that are fixed on the crane hack lever.The pulley (5) that has wherein comprised (in accompanying drawing 2) in the differential braking device (4), be fixed on backplate (7) upper end hemisphere universal joint (6) ratchet reel outer casing (7), one-sided ratchet reel (8) coils outside the ratchet reel that safety rope (9) is arranged, hypoid gear eclipsed form guide wheel (10) sour jujube bar (11), disc spring (12).

Fig. 2, differential braking device (4) structure chart
In conjunction with the accompanying drawings operation principle of the present utility model and structure are described further, the bracing frame (1) of protector is fixed on the crane hack lever, when the workman comes and goes when walking about aboard, brake apparatus (4) can slidably reciprocate on ropeway carrying-rope (3) by pulley (5), and keeps plumbness with the workman.The workman has upper and lower when mobile in the scope of operation, safety rope (9) is pulled out from brake apparatus (4), or in the ratchet reel under the effect of disc spring (12), by the tension of ratchet reel (8) rollback, rope can be because of on the long and cheat log barrier to the car like this.When the workman accidentally when work high above the ground face falls because the linear velocity of ratchet reel and sour jujube bar is different, brake and take place to disturb, braking distance is no more than 0.5 meter, thereby has guaranteed workman's personal safety.
Characteristics of the present utility model are these protectors, the kinetic energy that when adopting the buffering spring can absorb human body to fall at the two ends of ropeway carrying-rope safety rope is produced, reduced the pulling force load of safety rope, again little because of the short potential energy that produces of braking distance, the safety belt that ties up on the human body is little to the active force of human body soft tissue bone, should not produce internal injury. Reel is the braking of one-sided ratchet, make simple in structure, low cost of manufacture. The outlet guide wheel of safety rope adopts hyperbola gear overlapping formula structure, makes rope not press from both sides rope when operation, rubs that it is little to decrease, and pulley adopts the hemisphere universal joint to connect with substructure, and it is gone slick, the resistance that the minimizing rope moves.
This protector is easy to use, and is safe and reliable.
Technical parameter: 4 meters of bracing frame spans
18.5 millimeters of ropeway carrying-rope diameters
2.2 millimeters of safety rope diameters
8 meters of rope capacities
Braking distance＜500 millimeter
40 kilograms/millimeter of buffer spring rigidity
7 kilograms of differential braking device deadweights
Claims (2)
1, a kind of work high above the ground protector is characterized in that it is made up of bracing frame (1), buffer spring (2), ropeway carrying-rope (3), differential braking device (4).
2, work high above the ground protector according to claim 1 is characterized in that having comprised in the differential braking device (4) pulley (5) hemisphere universal joint (6), backplate (7), one-sided ratchet reel (8), safety rope (9), hypoid gear eclipsed form guide wheel (10), sour jujube bar (11), disc spring (12).
